The present application belongs to the technical field of industrial pollutant emission control and solid waste treatment, and particularly relates to a fly ash in-situ reduction method for waste incineration flue gas purification. A calcium-based composite powder is sprayed into a region with a temperature of 850-950 DEG C in the waste incinerator hearth by a spraying device.
